impact of brain connectome and personality on cognitive rehabilitation in multiple sclerosis

Conditions: Multiple Sclerosis

Summary: this study aims to apply baseline mri and neuropsychological measures to predict patient responses to behavioral cognitive rehabilitation. training will take place over 12 weeks, 1 hour per day, 5 days per week. the investigator hypothesizes the following: \[1a\] the investigator expects that individuals with low baseline conscientiousness will experience a lower magnitude of overall cognitive improvement following rehabilitation 1. b\] the investigator expects the impact of conscientiousness on fidelity of rehabilitation will in part be moderated by individual differences in program adherence and executive function 2. a\] the investigator expects that individual differences in structural and functional connectome disturbances will in part explain differences in participant responses to cognitive rehabilitation. this study will also serve to supplement the sample of participants for the current irb approved study ((irb: 603069, title: a case-control, 5-year follow-up study of cardiovascular, environmental and genetic risk factors for disease progression in patients with multiple sclerosis.

the participant will be asked to make a total of two (2) visits, approximately 90 days apart. each visit will involve: neuro-performance testing, and self-report questionnaires. each study visit is expected to take approximately 1-2 hours. between the two visits, the participant will be asked to complete a 12 week, computer-based cognitive training program. this includes 1 hour of training each day for 5 days each week. on visit 1, the participants will undergo a full battery of neuro-performance tasks including tests and questionnaires that will measure their memory, thinking speed, fatigue, and personality. this visit is expected to take approximately 1-2 hours. the participants will be also asked to have a close friend or family member to complete similar surveys. a self-addressed envelope containing these questionnaires will be provided to take home with them. the participant will need to pass it onto a close friend or family member to be completed and mailed back. in addition, the participant will be asked to take part in the 12 week computerized cognitive training program. this can be done at home, or anywhere the participant has access to a computer and internet. this cognitive training has been shown to improve cognitive performance in people with multiple sclerosis. the training involves a variety of interactive exercises which adapt to their abilities. the participants will need complete 1 hour of training each day, for 5 days each week. at 90 days, the participant will return for the 1-2 hours' follow-up visit where they will complete the same cognitive testing and questionnaires which they had completed during visit 1. all study visits will take place at buffalo general hospital. all of the procedures described above will be performed by a trained member of the research team as part of the research study. if an individual is ineligible for participation, their screening information will be discarded (i.e., shredded). if participants are deemed eligible (either in person or over the phone), they will be scheduled to come in to the hospital for neuropsychological testing. written consent will be obtained prior to administration of tests. as part of the consent process, participants will be asked for permission to use any data collected as part of the screening process as well.
